World No.11 Karolina Pliskova will replace world No.9 Lucie Safarova for the Czech Republic at Hopman Cup 2016.
In recent months Safarova has suffered from an abdominal muscle injury and spent a week in hospital due to a bacterial infection.
The 28-year-old needs extra time to regain full fitness ahead of the Australian Open.
“Unfortunately my health complications over the past few months are continuing and although I did all I could to be ready for the new season I’m not yet 100 per cent and I had to cancel my participation in Hopman Cup at this point,” Safarova said.
“I will be replaced by Kaja [Karolina] Pliskova and I will cheer for the Czech team.
“I continue my focus on recovery and training so I can still start my season in Australia.”
Pliskova will partner world No.41 Jiri Vesely when she makes her Perth debut in 14 days’ time.
In 2015, Pliskova won a singles title in Prague and was a finalist at tournaments in Sydney, Dubai, Birmingham, Stanford and Zhuhai.
The 23-year-old reached a career high of seven in August and was pivotal in the Czech Republic’s Fed Cup title win over Russia last month.
“We wish Lucie all the best with her recovery over the coming weeks and hope to see her on court in Australia soon,” Paul Kilderry, Hopman Cup Tournament Director said today.
“We welcome Karolina Pliskova to Perth for the first time and look forward to watching her and Jiri Vesely make their debut at Perth Arena for the Czech Republic.”
